MSM82C37B-5RS/GS/VJS
Clear First/Last Flip-Flop
16-bit address and word count registers are read or written in two consecutive operations
involving eight bits each (higher and lower order bits) under data bus port control. The fact that
the lower order bits are accessed first by the MSM82C37B-5, followed by accessing of the higher
order bits, is discerned by the internal first/last flip-flop. This command resets the first/last
flip-flop with the eight lower order bits being accessed immediately after execution.
Master Clear
The same operation as when the hardware RESET input is applied. Thus command clears the
contents of the command, status (for lower order bits), request, and temporary registers, also
clears the first/last flip-flop, and sets the mask register. This command is followed by an idle
cycle.
Clear Mask Register
When this command is executed, the mask bits for all channels are cleared to enable reception
of DMA transfers.
